Abstract
A process for carrying out a reaction in a reaction column, said process comprising: providing a first reactant to the reaction column in the liquid phase; contacting said first reactant with an excess of a second reactant such that reaction takes place within the reaction column to form a low boiling product and a high boiling product, at least a portion of said second reactant being provided to the reaction column in the vapour phase; recovering an overhead stream from at, or near, the top of the reaction column, said overhead stream comprising unreacted second reactant and the low boiling product; and recovering a bottoms stream from at, or near, the bottom of the reaction column comprising the high boiling product; wherein at least a portion of the heat required to vaporise the second reactant provided to the reaction column in the vapour phase is provided by heat exchange in a heat exchanger with a hot stream generated within the process other than a hot stream generated within the reaction column.
